16,2 Cockerell: Some Bees from Panay 147 
Nomada mindanaonis Cockerell. 
One female. Previously known from Mindanao and Palawan. 
The abdomen of the Panay example is clear red, and the insect 
is larger than those from Mindanao. 
Megachile subrixator Cockerell. 
Three females. 
Megachile hera Bingham. 
Three females. 
Megachile valdezi Cockerell. 
Two females. One has long black hair at extreme sides of 
third and fourth abdominal segments, in the other this is hardly 
noticeable. The specimens agree with the type of M. valdezi 
in being considerably larger than M. hera or M. subrixator. 
Megachile chlorura Cockerell. 
One female, 
Megachile metallescens Cockerell. 
Two females. 
Megachile megregori Cockerell. 
é One male. Differs from the type by having the hair bands at 
Sides of abdominal segments 2 to 4 suffused with fulvous. This 
may be the male of M. metallescens, which occurs in the same 
two localities. The abdomen is not at all metallic; but other- 
Wise, aside from the usual sexual differences, the insects are 
very much alike. 
Megachile rufofulva Cockerell var. panayensis var. nov. 
One female. Compared with the unique type from Mindanao, 
this is much more robust, with much broader thorax and abdo- 
men, and with more black hair on front and scutellum. Prob- 
ably a distinct subspecies is indicated, but more specimens are 
needed to prove the case. For the present we may designate 
the Culasi insect variety panayensis var. nov. The abdomen is 
like that of the Bornean M. sandacana Cockerell, but the thorax, 
Seen from above, appears shining black. 
The halictines from Culasi have been recorded in a previous 
Paper but I add the names to complete the list. 
ntialinte robbii (Crawford). 
alictus philippinensis Ashmead. 
ctus thoracicus sublustrans Cockerell.
